There is currently an access issue everywhere using CrowdStrike. The problem is that CrowdStrike servers with Auto Update are crashing to a Blue Screen after the latest #Microsoft update. The situation is bad globally, affecting many systems such as e-commerce, banking, and airlines. Physical access and intervention to servers are required to resolve the issue, which will take considerable time. In the meantime, you can apply the following solutions. 📢🟥 Solution 1: 1. Boot into Windows Recovery. 2. CD into your C:/ drive's System32/Crowdstrike folder. 3. Rename the file csagent.sys to csagent.sys.old (delete these two files). If this doesn't resolve the issue, try the following method: Solution 2: 1. Boot Windows into Safe Mode or the Windows Recovery Environment. 2. Navigate to the C:\Windows\System32\drivers\CrowdStrike directory. 3. Locate the file matching “C-00000291*.sys” and delete it. 4. Boot the host normally.
